Crozier and Ross: a dance on the ice
(As usual, a caveat about something being obvious to others but new to my simple brain)
'Captain Crozier and Miss Ross opened the ball with a quadrille"
Yes they did. But I also believe we have an actual picture of James and Francis dancing together.
This depiction by John Edward Davis (who is also responsible for the above quote) of the Ross Expedition's 1842 New Year celebration on the ice is my desktop background. I stare at it every day and the more I look at it, the more I love it.
Just look at those jolly pissed up sailors! The energy, the music, the hooting and grinning, the booze, the hat-waving cheers. it's WILD. It's pure joy.
And the dancing! The hand-holding dancing!
The figures of the men are hugely expressive. Not just their smiling and cheering expressions, their pipe-chomping, their coats variously unbottoned coat, but their bodies. Davis very deliberately depicts what it is their bodies are doing in their respective enjoyment of the festivities.
Also, wait — is that someone who's just floored it after slipping on the ice? And the suggestive snowy footprints leading away from the Ice Venus in the foreground? It's QUITE the scene.
The Dancing Captains
Some years back, in their fantastic post, @indifferent-century pointed to the two top hatted figures at the centre as very likely being James Clark Ross and Francis Rawdon Moira Crozier:
"And in the center we have two blue-coated and hat-wearing figures sitting seated on a high platform of snow."
HANG ON.... ARE they sitting?
Let's look at the energetic, leg-kicking dancing happening elsewhere in the scene. The men are holding hands in groups of three, five.. and four.
...It's the same arrangement. It's the quadrille.
You cannot convince me that isn't Francis and James DANCING the quadrille with two of their company. I would also put a bet on the lighter-haired figure on the right being Francis, either about to hold hands with James and the other smiling figure — or maybe slipping on the ice :D
ADDENDUM ON POSSIBLE NO-HOMO in the depiction of our two captains: I also noticed that whilst all the other dancing groups are holding hands, our captains are not. Perhaps whilst it was just about acceptable for Davis to depict his captains dancing (albeit face away), having them hold hands would have been a step too far.
Then again, as @sunflowerbower pointed out, the "Ross" figure IS holding up his coat in the same way the woman on the far right of the image above is holding up her dress.
Miss Ross. Holding up her "skirt".
